Which corrects the incorrect pronoun or contraction in the sentence? they're sister is happy to babysit, so you mustn't worry about it. a. their b. mustnt c. there d. must'nt

mine is hell,we all hate each other,we fight but me and my mom,dad,and siblings get along.

type of error:

the error in the sentence is a "dangling modifier". a dangling modifier is a phrase, word or clause that "dangles" because there is not target to modify. in this case, "after mopping the floor" is the dangling modifier since it has no word to modify. the noun "house" cannot mop the floor; therefore there is a mistake in the writing of the sentence.
